The point 0 is a non-isolated stationary point which is not a turning point nor a horizontal point of inflection as the signs of f ′ (x) and f″(x) do not change. The function f ( x ) = x 5 sin(1/ x ) for x ≠ 0, and f (0) = 0, gives an example where f ′ ( x ) and f″ ( x ) are both continuous, f ′ (0) = 0 and f″ (0) = 0, and yet f ...
Fermat's theorem gives only a necessary condition for extreme function values, as some stationary points are inflection points (not a maximum or minimum). The function's second derivative , if it exists, can sometimes be used to determine whether a stationary point is a maximum or minimum.
The x-coordinates of the red circles are stationary points; the blue squares are inflection points. In mathematics, a critical point is the argument of a function where the function derivative is zero (or undefined, as specified below). The value of the function at a critical point is a critical value. [1]
Hamilton's principle states that the true evolution q(t) of a system described by N generalized coordinates q = (q 1, q 2, ..., q N) between two specified states q 1 = q(t 1) and q 2 = q(t 2) at two specified times t 1 and t 2 is a stationary point (a point where the variation is zero) of the action functional [] = ((), ˙ (),) where (, ˙,) is the Lagrangian function for the system.
In calculus, Rolle's theorem or Rolle's lemma essentially states that any real-valued differentiable function that attains equal values at two distinct points must have at least one point, somewhere between them, at which the slope of the tangent line is zero. Such a point is known as a stationary point. It is a point at which the first ...

More generally, in the context of functions of several real variables, a stationary point that is not a local extremum is called a saddle point. An example of a stationary point of inflection is the point (0, 0) on the graph of y = x 3. The tangent is the x-axis, which cuts the graph at this point. An example of a non-stationary point of ...
The stars of college football have spent time with their loved ones, eaten their Christmas meals and opened their presents, but it’s now time to get back to the action.
